Given numbers are 945, 981, 843, 808
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(945, 981) = 103005
GCD(945, 981) = ( 945 x 981 ) / 103005
= 945 / 981
= 945
Step2:
LCM(9, 843) = 2529
GCD(9, 843) = ( 9 x 843 ) / 2529
= 9 / 843
= 9
Step3:
LCM(3, 808) = 2424
GCD(3, 808) = ( 3 x 808 ) / 2424
= 3 / 808
= 3
So, Greatest Common Divisor of 945, 981, 843, 808 is 1
